Diagnosis Procedure
- CHECK TIRE PRESSURE SENSOR ACTIVATION TOOL
Check tire pressure sensor activation tool.
Is the inspection result normal?
YES
GO TO 2 .
NO
Replace the battery of tire pressure sensor activation tool or repair/replace the tire pressure sensor activation tool.
- TIRE PRESSURE SENSOR ID REGISTRATION
Perform tire pressure sensor ID registration. Refer to Work Procedure .
CAUTION: To perform ID registration, observe the following points:- Never register ID in a place where radio waves are interfered (e.g. radio tower).
- Never register ID in a place close to vehicles including TPMS.
Is tire pressure sensor ID registration completed?
YES
Inspection End.
NO
GO TO 3 .
- CHECK TIRE PRESSURE SIGNAL
Change the work location and perform ID registration again.
NOTE: Depending on the tire pressure sensor position*, a blind spot exists, and the tire pressure receiver gets poor reception. If an ID registration is performed under this condition, the registration may not be completed. In such case, follow the instructions below to improve the radio wave receiving environment.- Rotate tire by 90°, 180°, or 270°. (This Step is to change tire pressure sensor position.)
- Open the door close to the tire of which ID registration is ongoing.
*: Radio wave reception condition depends on vehicle architecture (e.g. body harness layout, tire wheel design) or environment.
When ID registration is performed, which wheels do not react?
All wheels react and ID registration is possible.
Inspection End.
Only certain wheel(s) do not react.
Replace applicable tire pressure sensor. Refer to Tire Pressure Sensor .
All wheels do not react.
Replace low tire pressure warning control unit. Refer to Removal and Installation .
